Notes on Use
The OX400 is a product that conforms to the general safety requirements of the IEC standard. Be
sure to observe the following precautions when you operate it.
Handling Precautions
• Installation location
The OX400 is structurally non-explosion proof so you cannot use it in an explosive
atmosphere. Also, see 3.1, “Installation Location.”
• Power supply
Be sure to check that the power supply voltage specification of the OX400 matches the
voltage of the power supply before turning on the power.
• Protective ground
Be sure to connect the power plug of the OX400 to the 3P socket with a protective ground
pin in order to prevent electric shock.
• Fuse
Be sure to use a designated fuse in order to prevent a fire. Be sure to turn off the power
before replacing the fuse. Never use a fuse holder other than a designated one.
• Removing cover
There is a heated area inside the OX400, and touching it directly may cause a burn injury.
Never remove the cover except to replace the sensor.
• When opening the cover to replace the sensor, turn off the power switch, remove the power
plug from the socket, and wait for 1.5 hours or more before opening the cover.
